Claims (1)
位置する内燃機関のピストンにおいて、オイルリ
ング溝の下縁部に形成したオイル溜り溝と冷却空
洞に設けた突出部とを連通するオイル戻し孔を形
成し、そのオイル戻し孔の冷却空洞側の開口面を
ピストンの軸線とほぼ平行に形成したことを特徴
とする内燃機関のピストン。 In a piston of an internal combustion engine in which the lower wall of the cooling cavity is located below the oil ring groove, an oil return hole is provided that communicates the oil reservoir groove formed at the lower edge of the oil ring groove with the protrusion provided in the cooling cavity. A piston for an internal combustion engine, characterized in that the opening surface of the oil return hole on the cooling cavity side is formed substantially parallel to the axis of the piston.
